经鼻导管高流量湿化氧疗(high-flow nasal cannula oxygen therapy, HFNC)2014年在中国内地开始应用,短短几年内在临床上得到快速普及推广,其临床疗效得到临床医生的广泛认可,国际著名杂志近些年来也相继发表了多篇大样本前瞻性临床研究,证...
一、高流量呼吸机 高流量呼吸机(High flow nasal cannula,HFNC)是一种先进的呼气式呼吸机器,可以实现高浓度的氧气治疗。它的特点是可以提供比传统氧疗更高的氧浓度(40%-100%)和流速(60升/分钟),同时还可通过加热加湿的方式提供舒适的呼吸气体。通过调整氧流速和浓度,HFNC可以在提高...
经鼻高流量氧疗(humidified high-flow nasal cannula,HFNC)由空氧混合器装置、主动加温装置、加热导丝单回路管路、鼻导管组成。HFNC可提供恒定的氧浓度以及最高可达60~80 L/min的流量,其输送的气体经过加温加湿,可达到37℃、100%的相对湿度。因此与传统氧疗比较,HFNC克服了湿化不足和氧浓度不稳定等局限,具有更...
该共识主要针对经鼻高流量氧疗(High Flow Nasal Cannula,简称HFNC)在临床麻醉中的应用进行了规范化指导,旨在提高患者的舒适度和治疗效果。 HFNC是一种高流量、低湿度的氧气输送方式,通过鼻腔或口腔将氧气输送到肺部。这种治疗方法具有较高的氧浓度,能够减少患者因吸入高浓度氧气而产生的不适感。同时,HFNC还能降低呼吸...

Supplementary oxygen via standard nasal cannula (SNC) is the standard of care for most patients who undergo gastroscopy under general anesthesia, which provides oxygen flow up to 15L/min. High-flow nasal cannula (HFNC) could deliver oxygen at a rate up to 60L/min, which is recommended by ...
呼吸衰竭是临床上常见危急症,经鼻高流量氧疗(high flow nasal cannula oxygen, HFNC)和无创通气(non-invasive ventilation, NIV)氧疗是治疗呼吸衰竭的重要氧疗措施。HFNC和NIV均可改善呼吸衰竭患者血气分析指标,并降低患者呼吸功。临床研究证实,HFNC治疗低氧性呼吸衰竭 效果与NIV相当,但HFNC治疗高碳酸性 呼吸衰竭效果有...
To evaluate the respective impact of standard oxygen, high‑flow nasal cannula (HFNC) and noninvasive ventilation (NIV) on oxygenation failure rate and mortality in COVID‑19 patients admitted to intensive care units (ICUs). METHODS
Abbreviations: COPD, Chronic obstructive pulmonary disease; ICU, Intensive care unit; HFNC, High flow nasal cannula oxygen therapy; NIV, Non-invasive ventilation. The median COPD history of the enrolled patients was 8 years. The median time from the start of the current acute e...
High-flow nasal cannula (HFNC) oxygen therapy delivers adequately heated and humidified medical gas up to a flow rate of 60 L/minute and has the following physiological effects: anatomical dead space reduction, positive end-expiratory pressure (PEEP) effect, constant fraction of inspired oxygen,...
